Toks Olagundoye, who played the extraterrestrial Jackie Joyner-Kersee on ABC’s The Neighbors, is boarding the network’s Monday-night procedural in the series regular role of Hayley Vargas, TVLine has learned.

To be introduced in the two-part Season 8 premiere (kicking off Sept. 21), Hayley is described as a quick-witted, free-spirited, former Scotland Yard police officer who works as a security specialist and is not afraid to cross lines to get things done.
